Hi @russrimm ,
Could you please share a bit more about the error message that you mentioned?
Could you please show more details about the share link that you mentioned? Is it the App Url of a specific app?
How do you launch the app within your Mobile device? Using Launch function or open the App Url directly within your Mobile device browser?
Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned.
1. If you use the Launch function to launch your app:
Please check if you have typed a proper App URL within the Launch functon. The standard formula format as below:
Launch("https://web.powerapps.com/apps/e164446b-3f71-43d8-8f6c-fe35179b6d5e", "Param1", "Value1", "Param2", "Value2", ...)
Note: The "https://web.powerapps.com/apps/e164446b-3f71-43d8-8f6c-fe35179b6d5e" represents the App Url of your app. You could not append parameters to the App Url within the Launch function, the following formula is wrong:
Launch("https://web.powerapps.com/apps/e164446b-3f71-43d8-8f6c-fe35179b6d5e?Param1=" & TextInput1.Text) /* <-- Wrong formula */
2. If you open the App share link directly within your Mobile device's browser:
Please consider clear cache of your browser in your Mobile device, and then run the App Share link again, then provide your proper credentails to access this app, check if the issue is solved.
In addition, if you run your app using the PowerApps Mobile App in your Mobile device, please check if the version of the PowerApps Mobile App is the latest version in your Mobile device. If not, please consider upgrade it to the latest version, then try your app again, check if the issue is solved.
Also please consider uninstall PowerApps Mobile App from your mobile device, and then re-install it again, check if the issue is solved.
Best regards,
